Abstract

Die Erfindung betrifft ein interferometrische Einrichtung zum Nachweis einer Substanz mit strukturiertem, insbesondere periodischem oder quasiperiodischem Absorptionsspektrum und besteht aus einer Strahlungsquelle, in deren Strahlengang die zu untersuchende Substanz, ein Interferenzfilter, dessen Dicke den Abstand der Interferenzlinien bestimmt sowie ein Detektor angeordnet sind. Das Interferenzfilter ist ein thermooptisch abstimmbares Filter, welches aus einer Platte aus thermooptisch aktivem Material besteht, deren Stirnseiten teildurchlässig verspiegelt sein können. Eine Verschiebung der Durchlaßcharakteristik des Filters wird mit Hilfe einer Temperaturänderung des Filters erzeugt wird, wobei die Temperaturdifferenz ein Maß für die Verschiebung ist. Die Dicke der Platte ist so gewählt, daß der Abstand der erzeugten Interferenzlinien dem Abstand der Absorptionslinien der zu bestimmenden Substanz entspricht.
